You need a "quiet spot", where you can mark out a ring that's roughly 10 to 12 metres wide "using bayonets to mark the circle".

Bayonets are now probably optional, we'd wager.

The boxer would kick things off by asking for a spinner to come forth, and the ringie would place two or three coins on the kip, depending on the game.

"It was the ringie's job to ensure that the coins were tossed at least 10 feet (three metres) into the air, and that they spun well and were not "feathered" in any way," Heuston said.

All coins had to land within the circle.

The spinner had the right to continue spinning as long as they tossed heads.

If they tossed three heads in a row, the boxer would take their commission out of the centre (the guts) and the spinner could toss the kip or continue spinning.

These games could go for up to three or four hours, according to Heuston.

At the end of the game, punters would sometimes sling the boxer, to compensate them for the use of their facilities.

"As the game was held more often than once a week, you found that some of your customers went broke," Heuston said.

This is perhaps one of the good things about the Two-Up ban, which was put in place state-to-state because of the difficulties governments would have regulating the game and the potential for corruption.

"The boxer usually lent them enough for cigarettes and a beer until next pay," Heuston said.
